Sigma has announced two new lenses in their Fujifilm X Mount lens lineup. They aren’t lenses we haven’t seen before. They’re just new for Fuji shooters.
The two lenses now available in Fuji X mount are the Sigma 100-400mm f/5-6.3 DG DN OS Contemporary (buy here) and the Sigma 23mm f/1.4 DC DN Contemporary (buy here) lenses.
Sigma 100-400mm f/5-6.3 DG DN OS Contemporary
The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary lens, launched in 2020, has been available for Sony E and Leica L mounts since the start. Now, Fuji X mount joins the lineup. This isn’t the first zoom for Fuji that Sigma has announced. That honour goes to the 18-50mm f/2.8 DC DN Contemporary (buy here).
I do find it interesting that they went with a full-frame lens for the APS-C mount Fuji instead of developing a new APS-C zoom lens or updating older ones. I mean, Sigma, if you’re listening, mirrorless versions of the 18-35mm and 50-100mm f/1.8 Art lenses would do nicely, thanks!
Its introduction leaves a bit of a gap in the lineup. With Sigma’s f/1.4 primes ending at 56mm and this starting at 100mm, that’s a sizeable gap. Hey, maybe an updated 50-100mm f/1.8 Art will be next!
New Fuji Control Algorithm
Sigma says that the X mount version of the lens features a “control algorithm including AF drive and communication speed optimization” designed specifically for their X mount interchangeable lenses. So, they’re not just swapping out the mounts and repositioning a few wires. They’re actually optimising the lens code for system they’re being used with.
It supports both single and continuous-servo AF modes, as well as in-camera aberration correction (on supported cameras). The lens mount is also rubber sealed to aid in weather sealing, protecting your camera from rain and dust. The switches, too, have been optimised for Fuji use.
